Hi Massimo and Greg,
@Greg: if you yet returned your unit, you now have a solution ;)
I have not yet gotten rid of it, so thank you very much! It's a case of
download, extract, apply patch, and compile on my RPi, correct?
thanks for the effort for the patch!
welcome ;)

I applied your patch to the 2.6.5 code and run only the bcmxcp_usb
driver and... I'm not sure that everything is ok.
sorry, I forgot to explicitly request the trace (debug level 5) to
validate on my side...
If I run the driver as "./bcmxcp_usb -u root -a ups" it launches, but
after a second I get a "Communications with UPS lost: get_answer: not
the right sequence received 0!!!". However the driver seems still to
keep running.
I also tried to start the driver under debug (-DDDD). In attachment
you can see the output (until I typed ctrl-c), that also include some
some of the 'communication lost' messages.
the driver runs fine. you should get a good upsc output now.
the "Comm lost" msg are part of code adjustments needed, but the code
already handle this fine, and recovers (check "entering
get_answer(33)" for example).
could you please confirm this by sending the upsc output, and starting
upsmon to monitor on the RPi?
I'll let you know how I go!
Thanks,
Greg
